Comparative Example 2 is a vinyl forming the second layer of Example 1.
The same procedure as in Example 1 was carried out except that the glass transition temperature of the organosol resin-based paint was 40 ° C. In Comparative Example 3, the first layer and the second layer were both epoxy-urea resin-based paints, and two resin protective coating layers each having a dry coating thickness of 4 μm were formed. In Comparative Example 4, the first layer and the second layer were each formed of an epoxy / phenolic resin-based paint of E: P = 80: 20 to form two resin protective coating layers each having a dry coating thickness of 4 μm.

月経過後に缶胴内面の腐食状態を観察し、評価した。In Table 1, for the evaluation of workability, each coated piece coated with each of the above coatings is cut into a size of 70 mm × 70 mm, and the coated surface to be evaluated, that is, the inner surface of the can body is bent outward. Insert a spacer inside this and attach it to the impact tester, applying a load of 3 kg to 40 cm.
Drop from the height of and make impact bending. Next, the processed portion was immersed in a sulfuric acid cylinder solution, and the state of cracks in the coating film was observed and evaluated. To evaluate the corrosion resistance, fill each container with the above coating with 80% ethanol aqueous solution (water content 20%), hair mousse (water content 70%) and carbonated water, and then add a propellant. Fill and seal with a mounting cup. This was stored at a temperature of 45 ° C., and after 3 months, the corrosion state of the inner surface of the can body was observed and evaluated.

チール製エアゾール容器を提供できる。(Effect) As is apparent from the above description, the present invention provides that the first layer is formed of the epoxy / phenolic resin-based paint on the inner surface of the can body of the container.
~ 8μ, the second layer is vinyl with a glass transition temperature of 50 ° C or higher.
By coating 3 to 20μ of organosol resin-based paint to form a resin protective coating layer, it has excellent processability and corrosion resistance, and has a high coating protection effect. Even if it is filled with a water-based aerosol content and stored for a long time, corrosion and pores will occur. It is possible to provide a steel aerosol container that does not generate food.
更に、前記スチール製エアゾール容器に水分含有率が
20％以上であるウオーターベースのエアゾール内容物を
充填し、これを長期間保存しても支障のないエアゾール
